Computer Network

 Computer Network Topology Computer Network topology Arranging computers in a network is called topology Types of topology Bus topology Star topology Ring topology Mesh topology Hybrid  topology 1 Bus topology All the computers are connected to a single cable is known as bus topology Advantage of bus topology Less expensive Installation is easy Easy of configure Disadvantage If the cable fails , the complete network will fail,because all the computers are connected by a single cable. Data collisions Signal strength will be low,because more computers are connected. No security for the data transfer ,because every system is received the message 2 Star topology All the computers will connect to the centralized device(a single point) is called star topology.These centralized device can be either hub or switch.If the centralized device is hub the data transmission will be broadcast. Broadcast means message transfer will be available on all connected computers. If the centralized d...

  Introduction to computer networking - Explained for Beginners What is a Network? A computer network is a connection of several computers and devices that are linked together to communicate and share resources. In simple terms, a network allows one computer to connect with another computer. Purpose of a Network The main purpose of a network is resource sharing . Resource sharing means using resources from one computer on another computer through the network. Examples of resource sharing: Sharing files and documents Sharing printers Sharing servers Sharing software applications Sharing data Types of Computer Networks There are mainly three types of computer networks: LAN – Local Area Network MAN – Metropolitan Area Network WAN – Wide Area Network 1. Local Area Network (LAN) A Local Area Network (LAN) is a network that connects computers within a limited area . Examples: Within a building School or college Office Bank Main Purpose Sharing resources such as: Printers Soft...
